34 THE BUTTERFLIES OF THE 



manner of flying, which is usually in a north or south 

 general direction, the writer has thought that they did 

 not breed here, but that the larvae were to be found 

 farther south ; and this has in a measure been confirmed 

 by never finding any larvae or eggs on their food-plants. 

 The food-plant of a species determines to some extent 

 the places of its resort. Cabbage and turnips being 

 largely the food-plants of Pieris Eapce, this species will 

 be found more about gardens and fields where these 

 plants are grown. The tame and prairie grasses furnish- 

 ing food for the different forms of Satyrus Alope, this 

 species will be found in meadows and prairies ; while the 

 Neonymphas and Debis Portlandia, feeding more on the 

 grasses growing in shady woods, may be sought in these 

 places. The Neonymphas fly low and with a jerking 

 motion, unless disturbed, but Debis has a different flight. 

 The male selects some tree, on whose trunk he may be 

 found, darting out upon every intruder, large or small, 

 to return again to his post ; the female being near by, 

 perched upon a blade of grass or a leaf. The Theclas 

 are to be found in some open wood or on bushes along 

 the border of a clearing. They rest upon the sunny side 

 of a bush on a leaf, frequently flitting out and back again 

 to the same or an adjoining leaf; and Feniseca Tarquinius 

 has a similar habit. The Lycsenas are to be found more 

 about grasses and flowers, or hovering over some moist 

 place in the path or about some pool or small stream; 

 The different species of Pyrameis or Junonia are often 

 to be found in a path or road, from which they will fly 

 up to alight a short distance ahead, flying past you after 

 this is repeated a few times. Limenitis Disippus has a 

 similar habit, being found not far from some clump of
